[Dovecot-news] v2.2.29.rc1 released



Planning to release v2.2.29 on Monday. Please find and report any bugs before that.

  • When Dovecot encounters an internal error, it logs the real error and
    usually logs another line saying what function failed. Previously the
    second log line’s error message was a rather uninformative “Internal
    error occurred. Refer to server log for more information.” Now the
    real error message is duplicated in this second log line.
  • lmtp: If a delivery has multiple recipients, run autoexpunging only
    for the last recipient. This avoids a problem where a long
    autoexpunge run causes LMTP client to timeout between the DATA
    replies, resulting in duplicate mail deliveries.
  • config: Don’t stop the process due to idling. Otherwise the
    configuration is reloaded when the process restarts.
  • mail_log plugin: Differentiate autoexpunges from regular expunges
  • imapc: Use LOGOUT to cleanly disconnect from server.
  • lib-http: Internal status codes (>9000) are no longer visible in logs
  • director: Log vhost count changes and HOST-UP/DOWN
  • quota: Add plugin { quota_max_mail_size } setting to limit the
    maximum individual mail size that can be saved.
  • imapc: Add imapc_features=delay-login. If set, connecting to the
    remote IMAP server isn’t done until it’s necessary.
  • imapc: Add imapc_connection_retry_count and
    imapc_connection_retry_interval settings.
  • imap, pop3, indexer-worker: Add (deinit) to process title before
    autoexpunging runs.
  • Added %{encrypt} and %{decrypt} variables + imap/pop3 proxy: Log proxy state in errors as human-readable string.
  • imap/pop3-login: All forward_* extra fields returned by passdb are
    sent to the next hop when proxying using ID/XCLIENT commands. On the
    receiving side these fields are imported and sent to auth process
    where they’re accessible via %{passdb:forward_*}. This is done only
    if the sending IP address matches login_trusted_networks.
  • imap-login: If imap_id_retain=yes, send the IMAP ID string to
    auth process. %{client_id} expands to it in auth process. The ID
    string is also sent to the next hop when proxying.
  • fts-tika: Fixed crash when parsing attachment without
    Content-Disposition header. Broken by 2.2.28.
  • trash plugin was broken in 2.2.28
  • auth: When passdb/userdb lookups were done via auth-workers, too much
    data was added to auth cache. This could have resulted in wrong
    replies when using multiple passdbs/userdbs.
  • auth: passdb { skip & mechanisms } were ignored for the first passdb
  • oauth2: Various fixes, including fixes to crashes
  • dsync: Large Sieve scripts (or other large metadata) weren’t always
  • Index rebuild (e.g. doveadm force-resync) set all mails as \Recent
  • imap-hibernate: %{userdb:*} wasn’t expanded in mail_log_prefix
  • doveadm: Exit codes weren’t preserved when proxying commands via
    doveadm-server. Almost all errors used exit code 75 (tempfail).
  • ACLs weren’t applied to not-yet-existing autocreated mailboxes.
  • Fixed a potential crash when parsing a broken message header.
  • cassandra: Fallback consistency settings weren’t working correctly.
  • doveadm director status : “Initial config” was always empty
  • imapc: Various reconnection fixes.
